"We met Dan months before the project was scheduled to start and he knew our deadline was 7/9 when our first weekly vacation renter was due to arrive. Our main issues were: He was a week late starting Didn't show up on several days (had to take his son to get his COVID shot, several days it was too hot, heavy traffic, etc) Ignored my detailed instructions/drawings and we lost time because he plumed a double vanity for only 1 sink, told us we could buy any standard shower door from Lowe's only to learn AFTER the shower had been framed that it required a custom built door, forgot to tile the accent color stripe in the shower, miscalculated the amount of shower tile needed requiring me to drive 3 hours RT to purchase extra tile and deliver it to him. Skim coat on the ceiling was done poorly, the door to the bathroom didn't open all the way so we had to hire someone after Dan left to shave it down for us. He was supposed to finish by July 9th and didn't finish until Sept 9th!!!! had to give renters $3000 off because they had no toilet or shower. I split the difference with him and took $1500 off his bill and he was not happy. I should have taken the entire amount off. He might be OK for smaller jobs, but he is not focused enough and doesn't work a full day (usually 8 AM -1 PM) or even a full week. If he takes work outside of NH, he should have his plumbing/electrical license so he doesn't have to rely on outside contractors. We suffered because he didn't hold ME licenses and wasn't well connected w/ local contractors in ME."

FAQs for sump pump or interior foundation drains installation projects in Portsmouth, NH

Most residential pumps draw approximately 1,300 to 2,900 watts when they first start, then settle at roughly 800 to 1,050 watts during normal operation. The exact number depends on the motor’s horsepower and how often the float switch tells the pump to run. Even at the high end, the electricity cost is minor compared with the expense of cleaning up a flooded basement.

Grab a ruler and an empty 18‑inch‑wide pit. During a steady rain, time how much the water rises in one minute. Multiply that depth (in inches) by 60 to calculate gallons per hour, then add 50% for safety. If the result tops 2,100 gallons per hour—about 35 gallons a minute—you’ll need a 3/4‑horsepower unit. Anything lower, and a 1/3- or 1/2-horsepower pump should do the trick.

Loud rattling, constant cycling, or shuddering vibrations are the pump’s way of telling you it’s on its last legs. Musty smells, higher electric bills, and visible rust are other red flags. If the unit is 10 years old or older and exhibits any of these symptoms, replace it before the next heavy rain turns your basement into a wading pool.

You don’t have to hire a licensed plumber, but you should still bring in someone who installs sump pumps for a living—whether that’s a plumber, basement‑waterproofing specialist, or experienced handyman. They know the local codes, can wire the pump safely, and will test the system before they leave. Skipping professional help might void the warranty and could leave you with a pump that fails when you need it most.

Not every basement needs a pump, but if your home sits in a floodplain, has a high water table, or has ever taken on water during a storm, a sump pump is inexpensive insurance. For basements that only struggle with condensation or the occasional damp spot, sealing cracks and improving drainage may be all that is needed.
